Operation

UNIDEN UH8050S

UHF CB Transceiver

Setting the Manual Squelch

Turn the outer ring of the SQ control at the base to adjust the Squelch.

NOTE

You must select a channel which is not in use before setting the

SQUELCH control. (see p.19 for “Selecting a Channel”).

Think of the squelch con-

trol as a gate. If you turn

Squelch fully clockwise it

raises the‘Squelch gate’

so high that no signals get

through.

If you turn Squelch fully

counter clockwise it low-

ers the ‘Squelch gate’

so low that noise gets

through.

To set the ‘Squelch Gate’

to the desired level,

turn the squelch knob

counterclockwise until you

hear noise. Then care-

fully turn the Squelch knob

clockwise until the noise

fades. Now only strong

signals get through.
